razr and vx6700 ESN switching?

I’m planning of getting vx6700 to use at work and razr to use at home and in my free time that’s why I’m wondering what the online esn switching between these two phones is like. Has anyone used it in this combination? And also I won’t take a data plan if it has any reference to my question. Thanks

Well, I have 6700 and Razr V3c as a whole it works fine, but every time you want to switch the ESNs, you have to call cs as the online tool doesn’t work
